PIPE-CLEANER.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed January.l4, 1907. Serial No. 352,283.

\ To all whom it may concern:

Be it known that I, MORRIS E. KANALY, of Arlington, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Pipe Cleaners, of which the following is aspecification.

This invention has for its object to provide an improved device forcleaning the interior of the bowl of a smoking pipe in such manner as tothoroughly remove all ashes, and partly consumed tobacco, leaving theinner surface of the bowl cleanly and smoothly scraped.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,ligure 1 represents a perspective view showing my improved pipe cleanerready for use. Fig. 2 represents a perspective view showing the samereduced in length for insertion in a pocket. Fig. 3 represents aperspective view of the blade of my improved cleaner, and its shankremoved from the casing shown in Figs. 1 and 2. Fig.4 represents asection on line 4-4 of Fig. 1. Fig. 5 represents a side view of myimproved cleaner, and a sectiona view of a pipe bowl. 7

The same letters of reference indicate the same parts in all thefigures.

My improved pipe cleanercomprises a blade a and a shank b to which theblade is aflixed. The blade is composed of a single strip of resilientsteel bent into U shape, the ends of the strip being rigidly attached tothe shank b, which may be of any suitable material, such as vulcanizedfiber, wood, etc. The strip composing the blade (1 is relatively thinand uninterrupted from end to end, and presents U-shaped scraping edges,the form of the blade corresponding approximately to the form of theinterior of a pipe bowl. The flexibility of the blade is such that itsscraping edges conform accurately to the interior of the pipe bowl whenthe blade is pressed into the bowl, as indicated in Fig. 5, the sideportions of the blade normally standing farther apart than the internaldiameter of the pipe bowl, so that when the blade is forced into thebowl, its side portions will be sprung inwardly, and thus caused tospring outwardly toward the sides of the bowl in the effort of the bladeto assume its normal position. It will be seen, therefore, that when theblade is inserted in the bowl and given a rotary movement therein, thescraping edges will attack the accumulation of ashes, partly burnedtobacco, etc. in

the bowl, and bore or scrape the same away until the bowl is entirelycleaned. The blade may be rotated in either direction, so that each ofits scraping edges may be utilized.

0 represents a casing adapted to receive the blade and its shank, thecasing being preferably composed of sheet metal, and made of such lengththat the blade may be retracted within the shank, and protected thereby,as indicated in Fig. 2, the device being thus adapted for carriage in apocket. When the device is required for use, the blade is projected fromthe casing, as shown in Figs. 1, 4 and 5, the casing then acting as ahandle by which the blade may be rotated in the pipe.

Means are preferably provided for preventing the blade and its shankfromsliding inwardly into the socket when the device is in use, the meanshere shown comprising a spring catch 11, affixed to the shank b, andadapted to spring outwardly to engage one end of the casing c, asindicated in Figs. 1 and 4, the catch having a projecting end piece dstanding between the side portions of the blade, by which it may beforced inwardly to disengage it from the casing, and permit the bladeand shank to be moved inwardly, the shank having a recess behind theattached portion of the catch to permit the latter to spring inwardlysufhciently to enter the casing. When the blade and shank have beenwithdrawn to the desired extent, the catch springs outwardly intoengagement with the end of the casing, thus locking the blade and shankto the casing against pressure tending to force the blade into thecasing.

It will be seen that the described device is adapted to be readilyreduced to compact form for carriage in the pocket, and to be readilymade operative for use.

My invention is not limited to the particular form of shank and easinghere shown, it being obvious that these parts may be of any suitableform and construction, enabling the shank to'be adjusted relatively tothe casing, so that the casing will form a handle when the blade isprojected. It is also obvious that the blade and shank may be usedwithout the casing,'tl1e shank serving as the handle. The blade (1constitutes a flexible reamer which conforms automatically to theinterior of a pipe bowl.

I claim:

1. A pipe cleaner comprising a U-shaped resilient blade, a shank towhich the ends of the blade are secured, and a casing in which the bladeand shank are slidingly mounted.

A pipe cleaner comprising a II-shaped resilient blade, a shank to whichthe ends of the blade are secured, and a casing in which the blade andshank are adjustably mounted, means being employed for securing theblade and shank to the casing against pressure tending to move the bladeinto the casing.

3. A pipe cleaner comprising a Ushaped resilient blade, a shank to whichthe ends of the blade are secured, and a casing in which the blade andshank are slidahly mounted, the shank being provided with a spring catchadapted to engage one end of the casing, and prevent movement of theblade and shank into the casing.

4, A pipe cleaner comprising a flexible reamer formed of a singleuninterrupted piece of resilient meta] adapted 10 to conform to theinterior of a pipe bowl, and an operating handle therefor.

In testimony whereof I have nfiixcd my signature, in presence of twoWitnesses.
